The change in internal energy of the combustion of biphenyl in Kj is calculated as follows
=heat capacity of bomb calorimeter x delta T where delta T is change in temperature
delta T = 29.4 -25.8= 3.6 c
= 5.86 kj/c x 3.6 c = 21.096 kj
I'm not completely sure but if I did know I would definitely tell u
Maybe. Like in hitch hikers guide to the galaxy, I need to consult with the super computer
